Thank you for your interest in this product. Roland Sound Module Synthesizer JV-2080 [Included Items] Generic power cord I have confirmed sound output from the headphone jack using a MIDI keyboard. The battery for saving tones has been replaced with a new one. Expansion boards were recognized. There are signs of use such as scratches and dirt. Expansion boards are not included. Display, buttons, and VALUE dial operate well. This is a multi-functional instrument. Not all functions have been checked. How about this for those who want the sound of 90s Roland on a real machine, not a software synthesizer? After a simple cleaning, it will be packed with bubble wrap and recycled cardboard for shipping. The listing may be removed without notice. Thank you for reading to the end. Thank you for your consideration.
